SPECIFCATION forming part of 'Letters Patent N o. 605,466, dated June 14, 1898.

Appl-muon filed March 29, 18197'.

To all whom t may concern:

Beit known that I, AMOS H. BARNES, a citizen of the United States, residing at Reno, in the county of Washoe and State of Nevada, have invented certain new and useful linprovements in Locks; and I do hereby declare that the following is a full, clear,`and'exact description thereof.

The present invention relates to a certain` new and useful door-lock, and more especially to that class known as 1nortise-locks; and it consists in the arrangement of parts and details of construction, as will bev hereinafter1 fully set forth in the drawings and described and pointed out in the specification.

The object of the invention is to provide a simple and inexpensive lock which( shall be so constructed that as the lock-bolt is thrown outward the latch-bolt will be looked against' inward movement.

In order fully to understand the invention,

I reference must be had to the accompanying sheet of drawings, forming a part of this application, wherein A Figure l is a top plan view of the lock with the faceplate removed, showing the position of the parts when the lock-bolt is `thrown inbroken sectional View showing the lock secured within the mortise of a door. ,t

In the drawings the letter A is used to indicate the frame or casing for'the lock noechf anisin. Vithin the frame or casing is located the slide or latch bolt A', the outer end of which works through an opening formed in the edge d of the traine or casing. This slide or latch bolt is held pressed outward by the fiat steel spring c', which bears against the rear or tail end of the said bolt. The ends o2 of this spring are slightly curved and bear against the studs or pins o3, upwardly pro.- jecting from the base-plate of the frame or casing. This latch-bolt is thrown inward or operated by the turning of the door knobs orhandles A2, secured upon the ends of the square shank B, which extends through the easing and guide B. This guide is fitted within the slot b,#cut in the latch-bolt, and is provided with the side wings b', which wings frnent. means of the guide-screw "f4, which'ektends .through the slot f', cutin theslideetuinbler, and screws into the bottoinplate of the frame serial-N0. 629,749. (mman.)

or lugs as the door-knob isL turned bear lagainst Ithe face b2 ofthe slideor latch bolt and' force the saidV bolt inward, the `tension or, pressure of the spring a being sufficient to move the same outward when the door-kn ob is released.-

. Below the latchfbolt is arranged the lockbolt B2, the outer end of .which works through an opening formed inthe edge o of :the frame or casing A. This bolt is cast with a :rib b3, so as to make the .upper face of the said bolt come iush` with the edge of the casing or frame. The lower edge 'of the lock-bolt is formed with the notches d CZ and rests upon the pin or stud cl2; upwardly projecting from the base-plate or the frame or casing, being held downward by the spring C. This spring is connectedto the stud cl3 and the free end thereofpasses beneath l the stud e and bears `upon the upper edge of said bolt, so as to hold `the same pressed down upon Athestud or pin d2 and prevents itsbeing jarred 'outof posi- 4tion during 'the' handling of the lock'. rBhe lowerinner end portion of this bolt is also cut away in order toA forni two shoulders e e2,

`with which the bit of the key engages, so as to throw'the bolt B2i'orward andfbackward.

At, the rear of the lock-bolt is'arranged the holds the latch-bolt against inward move- This `slidetuinbler is held in 'place by or casing, andsaid slide-tumbler is cast with an inwardly-projecting liange f2, the edge of which is cut away, so as to provide the shoulders l 2, which are engaged by the bit g of the key, so as to throw the tumbler in order to lock or release the'l latch-bolt'as the same is turned to lock or release the slide-bolt.

The inner edge of the slide-tumbler is cut away, as shown at- 3, 'and rides,`as`raised or lowered, upon the stud g', upwardly projectn ing from the bottom plate of the, casing or frame, being held against said studby the pressure of the spring D, which is secured to the pin g2 and extends downward and bears against the outer edgeof the slide-tumbler C.

At the lower portion of the casing is located IOO `- said bolt outward.

the longitudinally-movable lock-bar D',which bar, when the slide-tumbler is thrown upward, moves beneath the slide-tumbler and holds the same upward until the key is turned to throw it out of engagement with the tumbler. This lock-bar is cutaway near its outer lower edge, so as to present an inclined shoulder or edge g3, which rides upon the stud h as the lock-bar is thrown forward and backward. The lock-bar is held downward by the spring D2, which is attached to a pin 7i', upwardly projecting from the bottom plate of the casing, the free end resting within a groove h2, cut in the upper edge of said bar. The inner end portion of the lock-bar is reduced and moves beneath the guide-piece j. In the upper edge of the lock-bar is cut a socket which forms the shoulders j j?, against which the bit of the key bears as turned to throw the lock-bolt inward or outward.

The latch-bolt as moved inward or outward rides upon the guide-screwjs, which extends through the slot ,7'4 cut therein into the bottom plate of the casing.

To the bottom plate of the casingis secured, above the latch-bolt, the turn-pin E, the outwardly-projectingleaf or bit 7e of which when thrown downward engages the shoulder 7c' at the inner end of the latch-bolt and locks the latch-bolt against inward movement. This pin has a cross-slot 762 cnt in its'upper end and is operated by a flat key, which is inserted through an opening cut in the faceplate of the casing or frame and fits within the cross-slot.

In the jamb of the door E, Fig. 3, on the inside, is iitted the guide-thimble E2, which is arranged in line with the opening Z of -the faceplate L. Through this thimble the key is inserted for operating the turn-pin. This pin serves as a night-catch for locking the latchbolt independent of the slide-tumbler.

When the parts are in position illustrated by Fig. 1, they are thrown into locked position, Fig. 2, by turning the key, so that the bit g is forced'against the shoulder l of the slide-tumbler, which throws the said slidetumbler upward against the latch-bolt A', back of the shoulder f. As the bit g moves away from the shoulder lit bears against the shoulder e of the lock-bolt B2 and forces the (Position illustrated in Fig. 2.) Continuing its movement the bit g is brought to bear against the shoulder j of the lock-bar and forces the said bar inward beneath the lower end of the slide-tumbler. Turning the key in an opposite direction the bit g first engages the shoulder I7'2 of the lockbar, forcing it outward, then the shoulder e2 of the lock-bolt, forcing'it inward, and then the shoulder 2 of the slide-tumbler, forcing it downward.

In my lock it will be observed that by one turn of the key I either lock or release both the lock-bolt and the latch-bolt.

Having thus described my invention, what I claim as new, and desire to secure protec- -tion in by Letters Patent, is-

1. In a lock, the combination with a case having av keyhole, of a horizontally-sliding latch-bolt provided on its under side with a shoulder f, a vertically-sliding tumbler adapted in its raised position to engage said shoulder and hold the latch-bolt from inward movement, a horizontally-sliding lock-bolt below the latch-bolt and above the keyhole and on the same side of the vertically-sliding` tumbler as the keyhole, and a horizontally-sliding lock-bar below the keyhole of a length when thrown back to extend under the vertically-sliding tumbler when the latter is raised and hold it in engagement with the shoulder f, said lock-bolt, tumbler, and lockbar adapted to be operated by a key in said keyhole, substantially as described.

2. In a lock, the combination with a case having a keyhole, and the latch-bolt, of a sliding lock-bolt situated between the latchbolt and the keyhole, a slidingtumbler moving in adirection substantially at right angles to that of the lock-boltand adapted to hold the latch-bolt from inward movement, and a sliding lock-bar situated on' the side of the keyhole opposite the lock-bolt and moving in a direction parallel with that of the lock-bolt and adapted to holdl the sliding tumbler from movement, said lock-bolt, tumbler and lockbar being adapted to operate by the key.

In testimony whereof I affix my signature, in presence of two witnesses, this 3d day of February, 1897.

AMos n. BARNES.
